About the Company
Our client is a Series B technology company building an intelligent KYC and enhanced due diligence platform used by financial institutions and compliance-focused organisations. They operate in a high-stakes, regulated domain, combining entity resolution, risk analysis, and real-time screening into a sophisticated data intelligence product. Backed by institutional investment and growing fast, this is a company solving hard problems at scale... with the engineering rigour to match.
The Role
You will join a lean, high-calibre engineering team working directly on the core platform. The role spans backend and frontend, with a natural lean towards the API and service layer... you will own features end-to-end, from early architecture decisions through to production deployment. The team moves quickly and expects engineers who can operate independently, challenge assumptions, and raise the quality bar without being asked. Prior experience in regulated environments is a genuine advantage; if you understand why data integrity and audit trails matter, you will feel at home here immediately.
